APPARATUS FOR PRODUCING A GASEOUS REACTION.

Specification of Letters Patent.

'2' may nccrn: desirable dielectric material. The lower that I, FRANK W. PEEK, r., head 6 is made in two sections 8 and 9 which a citiren of the United States, residing at may be conveniently secured together by a t cliencctady in the county of Schenectady threaded joint 10 which is made air-ti'ght 5 State of New York, have invented certain by a suitable packing ring 11. The lower new and useful Improvements in Apparatus section 8 of the head is cored out at 12 to tor Producing a Gaseous Reaction, of which receive a. plate 13. This plate, which the following is a speciti *ation. made of a conducting material, such as iron,

My invention has retcrence to an appatogether with the dielectric formed by the 10 rains for producing a gaseous reaction by head 6, which is preferably made of a mawhat known as a silent discharge. and is terial having a better conductivity than does particularly applicable to the production of air, forinsa path for the static coarge beozcn In a device of this character a static tween the edge of the electrode 1 and the discharge takes place between electrodes beelectrode 2 which passes below the dielectric 1-5 tween which disposed a dielectric, and 3, thus relieving the edge of this dielectric when the electrodes are equally spaced apart from the static stress to which it would throughout, there is a tendency tor the static otherwise be subjected. he plate 13 is procharge to concentrate at the edges of the yidcd with an annular series of openings 1% elcctrodci, under which conditions the di near the inner electrode The upper head 20 electric material liable to be punctured. 7 is cored out allow: at 15 and is inwardly One object of my intention the prorithreaded to receive a plug 16 Which engages sion of means for preventing this conccntrapacking ring and forms an air-tight joint tion of the static charge at the edges of the with the head.

Air or other gas dielect i .nd the outer and inner electrodes which is to be acted upon is led into the 109 respceti' ly. The generator is supported in ozone generator through a pipe 19 which position from the inner electrode-2 which is enters the space between outer electrode longer than the t ofthe ozone unit. The l and the dielectric, and a pipe 20, which electrodes and the diclcctri are held in poconnnunicates with the space between the in- 00 sition by two heads 6 and 7 which are proher electrode and the dielectric, carries away vided with central openings which fit snugly the ozone, or othergas Which has been proover the inner electrode 2 and are held in duced. Conductors 21 and 22 are electriposition either frictionally as shown or by cally connected to the outer and inner elec- V set screws or in any desirable manner. These trodes respectively and are connected to any 25 heads are made of Wood or porcelain or any suitable source of electric energy for pro- 510 electrode and the dielectric 3. YVithin this space the air, in case of the production of ozone, is partially ozonized and passes on through the openings 18 to the space 5 between the inner electrode and the dielectric where the gases are again subjected to the discharge taking place between the electrodes and where the amount of ozone is still further increased. The ozone then passes through the openings 1% in the plate 13 to a recess below the plate and is led ed by the pipe 20.

It will be understood that any desired means, such as a fan, or an injector, may be utilized for the purpose of producing the necessary movement of gases through the generator.

\Vater or air or any other desired cooling mediummay be passed through the electrode 2 for the purpose or" keeping the working parts of the generator at the desired temperature.

lVhile I am not limited to the use of such materials for the electrodes, I have found that electrodes made from aluminum are suitable for the purpose of my invention, :id have. further found that by electrolytic.. y coating the surfaces between which the discharge takes place '1 that is, the inner surface of the outer electrode and the outer surface of the inner electrode, with a layer of aluminum hydroxid,a very smooth durable surface is produced which is well suited for the purpose of my invention. It is also to be understood that, while I have shown my invention in connection with cylindrical electrodes, it is not limited to such form of electrodes, but is equally applicable to any electrodes between which the discharge space is substantially uniform.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an apparatus for producing a gaseous reaction by a silent discharge, a pair of electrodes between which a static discharge takes place, a dielectric located between said electrodes and means independent of the electrodes for preventing the concentration of a static charge between the edges of the electrodes.

2. In an apparatus for producing a gaseous reaction by a silent discharge, a pair of electrodes between which a static discharge takes place and a conducting member located adjacent the edges of the electrodes for preventing the concentration of a static charge between the edges of said electrodes.

3. In an apparatus for producing a gaseous reaction by a silent discharge, a pair of electrodes between which a static discharge takes place, a dielectric member disposed between the two electrodes and a conducting member arranged adjacent the edges of the electrode for preventing the concentration of a static charge between the edges of said electrodes.

4.. In an apparatus for producing a gaseous reaction by a silent discharge, a pair of electrodes between which a static discharge takes place, a dielectric member arranged between the two electrodes and means for maintaining said dielectric member in posi' tion comprising a yieldingly supported conducting member engaging one end of the dielectric.

5. In an apparatus for producing a gaseous reaction by a silent discharge, a pair of concentrically arranged electrodes between which a static discharge takes place, a dielectric member arrangcd between the two electrodes, a stationary conducting'member engaging one end of the dielectric member and a yieldingly supported conducting plate engaging the other end of the dielectric.

6. In an apparatus for producing a gaseoutreaction by a silent discharge, a pair of electrodes between which a static discharge takes place having their discharge surfaces coated with aluminum hydroxid.

In witness whereof, I have hereunto set my hand this 21st day of June, 1911.
